I do these trades a lot. I’d say be prepared to hold through the next week or 2. I’ve seen them top the day of the addition but also a week or 2 later. Vanguard doesn’t buy all their weighting in one day, they also buy it before and after the add date so sometimes it chops higher a bit. Next week is the weakest week seasonally of the year so could also get a market dip to help out

I think best to short it tomorrow prior to the close (to avoid getting whipsawed, potentially) and holding for the next couple of weeks. Closing if you get stopped out.

There is data that suggests if a stock is a genuine addition to an index (eg new listing), the stock stays up it seems
